Description
Technical field
The present invention relates to heating technology fields, and in particular to a kind of carbon ground cushion and its production technology.
Background technique
Floor heating is the abbreviation of floor panel heating, and it be with entire ground is scattered that English, which is Radiant Floor Heating,
Hot device is evenly heated entire ground by the heating agent in flooring radiation layer, is radiated upwards using the accumulation of heat on ground itself and heat
Rule conducted from the bottom to top, to achieve the purpose that heating, meet the fitness theory of Chinese medicine " temperature foot and push up cool ", be current
The heating system of the most comfortable.
A ground cushion flexible can be placed in initial floor panel structure, below floor, play the role of transition, have simultaneously
There are noise reduction, waterproof and other effects；The heating of floor heating later gradually comes into vogue, and common ground cushion can hinder heat to be communicated up, people
Invent the place of cork doping metals silk or clipped wire, it is intended to improve the thermal conductivity of ground cushion, but cork sheet is as heat-barrier material,
Only proceed to conduction by wire or clipped wire, rate is slow, efficiency is also low；People use multiple with leachy place still later
Waterproof membrane is closed to improve heat transfer property, but the presence of waterproof membrane more or less hinders the propagation of heat, ground heating system is led
Thermal velocity and efficiency are not ideal enough always.
Application publication number is that the Chinese invention patent of 105217608 A of CN discloses a kind of graphite guide hotting mask, thermally conductive speed
Rate is fast, high-efficient, is suitable as the ground cushion of ground heating system, but graphite material matter itself is soft and toughness is low, for a long time using fragile
Broken deformation；And composite human body characteristic itself is heated in floor heating, advantageous to human health, common graphite guide hotting mask does not make full use of
This point develops the ground cushion for being more advantageous to body-care.
Summary of the invention
The purpose of the present invention, be to solve the above-mentioned problems, provide a kind of heat conduction rate quickly, high-efficient, intensity is enough
